Venturi Scrubbers - this is a device designed to clean outgoing gases from dust, dusty particles, smoke, aerosols and various impurities. Dusty particles are captured due to their wetting, and then deposited in a drop trap.
Venturi scrubbers consist of: inlet pipe, confuser fluid supply nozzle, diffuser, neck, drop catcher, outlet pipe, sludge outlet node.
Below are photos of Venturi scrubbers

The operation of this type of scrubbers is based on the Venturi pipe, as well as on the basis of the Bernuli equation, according to which the greater the difference in cross-sectional area at the inlet and outlet of the confuser, the higher the speed, the smaller the difference in cross-sectional area at the inlet and outlet of the confuser, the lower the speed. Polluted gas vapors enter the Venturi pipe. Further, this gas develops a high speed, as the cross-sectional area decreases, and the speed of gas flows increases. After that, water is supplied through special nozzles to wet the dusty particles. This water is crushed into many small droplets, the contact area of water with gas increases, dusty particles are wetted and stick together, and then removed from the droplet collector in the form of sludge by draining.The air purified from impurities and dust enters the atmospheric air and does not pose a threat to environmental pollution.

Advantages of Venturi scrubbers
Venturi scrubbers have many advantages over other wet gas cleaning devices, namely:
1) Scrubbers have a very high degree of purification up to 99 percent
2) They have a relatively low cost, which significantly reduces the cost of their acquisition.
3) Venturi scrubbers are distinguished by their durability and reliability
4) They are suitable for all types of pollution, and are also suitable for humidifying the air.
Application of Venturi Scrubbers in various industries
Venturi scrubbers are actively used in metallurgy, mechanical and thermal processing of materials, energy industry, food industry, agro-industrial sector.
Venturi scrubbers are capable of capturing the following types of pollutants: sulfur oxide, nitrogen oxides, hydrogen sulfide, hydrogen chloride, hydrogen bromide, ammonia, thiols, mercaptans, acid and alkaline vapors, aldehydes, metal oxides, halogens, halides, esters, alcohols, alkanes.
Venturi scrubbers are the best and most common gas cleaning equipment in the world and the best solution for cleaning gases from pollutants.
